[jdom-interest] variable evaluation in XPATH expression

[Alastair Rodgers]

Something like the following should do it:

XPath xpath = new JDOMXPath("/*/*/subcategory[@mappedname=$map]");
SimpleVariableContext vars = new SimpleVariableContext();
vars.setVariableValue(null, "map", "europe");
xpath.setVariableContext(vars);
Element result = (Element)xpath.selectSingleNode(doc);


Al.

Hi all,

String map="europe";
XPath servletPath = XPath.newInstance("/*/*/subcategory[@mappedname=map]");

Iam eagerly waiting for reply...
